But it's not win-win-win when somebody can propose something that exclusively enriches a certain few people, and those certain few people have enough power to make that proposal effective. This is an effective kleptocracy, and I don't think that anybody really wants to be associated with that.
I won't comment on the whole post, but you are mistaken about the meaning of the 10% threshold for approving proposals. It is not realistic for Evan & the rest of the Core team to past a self-serving proposal against the wishes of the rest of the community since the formula for approval is
YES VOTES - NO VOTES > 10%. In other words, so long as Evan and Core own less than 54.9% of the MNs (since 54.9% - 45.1% = 9.8%) they can't do anything like you describe above. And no, there is zero evidence that they own even 1000MNs much less than the approx 2400 nodes you would need for that attack.
The current system may indeed have yet undiscovered flaws, but a small group of people with a lot of MNs overriding the wishes of the entire community is not one of them.
